Application filed Gctober 20, 1913. Serial No. 796,118.

To aZZ whom it may concern Be it known that 1, JOHN MITTERMEYER, a citizen of the United States, residing at Rice Lake, in the county of Barron and State of Wisconsin, have invented certain new and useful Improvements in Car-Stakes, of which the following is a specification.

This invention relates to stakes employed on logging cars for holding the load in place on the bunks of the car.

The invention has for its object to provide a car stake which is readily removable to facilitate the unloading of the logs, and

also to provide a lock for the stake which firmly holds the same in upright position.

A further object of the invention is to provide a novel and improved trip device for the look, by which the stake may be quickly released, and without endangering the operator, the trip device being operable from a point remote from the stake to be released.

These objects are attained by means of a combination and arrangement of parts to be hereinafter described and claimed, and in order that the invention 'may be better understood, reference is had to the accompanying drawings in which Figure 1 is a cross-section of a logging car showing the application of the invention; Fig. 2 is a plan view thereof, and Fig. 3 is a perspective view.

Referring specifically to the drawings, 10

denotes the sills of the car on which the bunks 11 are supported. Inasmuch as the structure of the car is immaterial to the present invention, a detailed description thereof is deemed unnecessary. On one end of the bunk is mounted a stake 12 for holding the logs on this side of the car, said stake being removable to facilitate the unloading of the logs. The other end of the bunk may be equipped with any suitable means for holding the logs on the corresponding side of the car. One bunk and stake only have been shown, it being understood that each bunk is equipped with a removable stake and the locking and releasing means therefor to be described hereinafter.

On the sides of the bunk 11, adjacent to the end having the removable stake 12 are rigidly secured metal plates 13. These plates project from the end of the bunk to form a pocket to hold the stake, the. latter seating between said projecting portions of the plates. On the outer face of one of the plates is fastened a short bar 1 1 having its outer end formed with an eye 15 which projects' from the outer end of the plate and carries a retaining member for the stake, said member comprising a cross-bar 16 adapted to be placed across the outer ends of the plates in front of the stake. From the outer face of the stake projects apin 17 which rests on top of the cross-bar 16 and prevents the stake from slipping down in the pocket.

The cross-bar 16 is loosely connected at one end to the eye 15, and its other end has an eye 18 in which'is carried a link 19 which is adapted to be slipped over a lug 20 outstanding from the plate 13 which is opposite the plate carrying the bar 14. Means, to be presently described, are provided for locking the link on the lug, whereby the cross-bar 16 is secured in a retaining position and the stake is firmly held in the pocket.

The locking means for the link 19 comprises a plate 21 which is pivoted at one end on a bolt 22 carried by the plate 13 which has the lug 20. The pivot bolt 22 is located a short distance to the rear of the lug, and the plate is designed to be swung over the outer face of the lug to prevent the link from slipping off the same. An operating rod 23 is connected to the plate 21, said rod extending toward thatend of the bunk 11 remote from the stake 12, and terminating close to said end so that the plate may be actuated with safety to the operator. A short section of chain 24 is connected to the outer end of the rod. Intermediate its ends, the rod 23 passes under a guide 25 carrying a cross-pin 26 adapted to seat in, a notch 27 in the lower edge of the rod, whereby the rod is held against longitudinal movement to actuate the plate 21. A pivoted dog 28 carried by the bunk 11 is engageable with the rod to hold the same in locked position. Before the rod can be actuated, the dog must be swung to clear the same, after which the rod may be lifted to clear the pin 26. The rod is now unlocked and may be moved in the direction of its length to actuate the plate 21.

The pivoted end of the plate 21 has an enlargement 29 which is formed with an incline 30 extending spirally from the base, at which latter is a sharp edge 81. The edge of the part 29 is eccentric to the pivot 22, the base of the incline being nearest to the pivot and such a distance therefrom that it is spaced from the rear end of the lug 20 just enough to allow the link 19 to seat thereon. The distance of the eccentric edge of the part 29 from the pivot gradually increases so that when it is rotated a sufiicient distance to swing the plate 21 off the lug, that portion of the incline which is on the same level as the outer face of the lug comes against the rear end of the latter.

The part 29 is designed to automatically trip the link 19 off the lug 20 when the plate 21 is swung to release the link. In locking position, the link being on the lug, the plate 21 engages the outer face of the lug and thus prevents the link from slipping off. The sharp edge 31 is now close to that portion of the link which extends around the rear end of the lug, and slightly behind the same, the incline being grooved to accommodate said end of the ring. If new the plate is swung away from the lug, the part 29 turns and the incline 30 wedges the ring off the lug, which releases the crossbar 16 and allows the same to swing down to release the stake 12, the weight of the logs bearing on the latter causing it to drop forward out of the pocket and thus releasing the logs.

When the plate 21 is in position to lock the link 19, the pin 26 seats in the notch 27 and upon swinging the dog 28 down against the top edge of the rod 23, the latter is locked so that the link cannot become accidentally disengaged from the lug 20.

The device herein described provides a safe and strong lock, which can be safely, easily and quickly operated.

I claim:

1. The combination with the bunk of a logging car, of plates secured to the sides and projecting from one end thereof, a stake loosely mounted between the projecting ends of the plates, a cross-bar loosely carried by one of the plates and adapted to be extended across the outer ends of the plates to confine the stake therebetween, a lug on the other plate, a link carried by the free end of the cross-bar and engageable over the lug, a swinging member adapted to be positioned over the outer face of the lug, an actuating rod for said member, and means for locking said rod.
